Ngā mira mutunga carbideHe mea nui ēnei taputapu i roto i te umanga mīhini. Nā te pakari me te tika o ēnei taputapu, kua waiho ēnei hei whiringa tuatahi mā te tini o ngā tohunga. I roto i tēnei pou rangitaki, ka matapakihia e mātou te hiranga o ngā mira pito waro me pēhea e taea ai e rātou te whakapai ake i ngā hua o tō mīhini.
Ngā mira mutunga carbide, e mōhiotia ana hoki kongā mira mutunga carbide, he taputapu tapahi e whakamahia ana i roto i ngā mahi mira. He mea hanga ēnei mai i tētahi matū e kiia nei ko te carbide, he ranunga o te waro me te tungsten. He tino pakari tēnei rauemi, ā, he ātete ki te kakahu, he mea tino pai mō te mira i ngā rauemi uaua pērā i te maitai kore waikura, te maitai whakapakeke me te rino maka.

Ko tētahi o ngā painga nui o ngā mira pito waro ko tōna kaha ki te noho koi mō te wā roa. Nā te pakeke o ēnei taputapu, ka taea e rātou te tu atu ki ngā tere tapahi teitei, ka whakaiti i te wā kore mahi e hiahiatia ana hei whakawhiti taputapu. He mea nui tēnei hei whakapiki i te hua me te whai huatanga o ngā mahi miihini.
Hei tāpiri, he nui ake te ātete wera o ngā mira mutunga carbide i ērā atu momo mirangā mira mutungaKo te tikanga o tēnei ka taea e rātou te tu atu i ngā pāmahana teitei e puta ana i te wā e miihini ana, e ārai ana i te pakaru o te taputapu, te pakaru wawe rānei. Hei tāpiri, ko tōna ātete wera pai ka whakaiti i te whānui o te wera, ā, ka whakapai ake i te tika o ngā āhuatanga o ngā wāhanga miihini.
HRC60 mira mutungahe momo mira mutunga carbide motuhake kua whakapakeketia ki te pakeketanga Rockwell o te 60. Mā tēnei taumata pakeke ka roa ake te mau me te mahi tapahi.Ngā mira mutunga HRC60e whakamahia ana i ngā mahi e hiahia ana kia miihinihia ngā rauemi uaua, kia miihinihia rānei i te tere teitei.
